The resetting mode (manual or automatic) can be
chosen. The termal relays have a double side-system
which operates the switch-off mechanism, in case of
phase failure. It releases faster: within 2 hours at 15 %
overload. The contacting mechanism contains two
electrically independent NO and NC contacts.

4.1 MH type mini thermal relay
The mini thermal relays are produced in the current-range
of 0,11 A...14 A. They can be plugged directly to the lower
terminals of the MK 2- and MK 4- type minicontactors, they
cannot mounted independently to a plate or rail.

The current-range are avaible from 0,2 A to 32 A covered
by 13 differently set devices. Mounting is possible to 35
mm rail (snap-on) or fixed with three M4 screws to a
mounting plate. The device can be plugged directly to
lower terminals (2T1, 4T2, 6 T3) of DL-K4, DL-K5, DL-K7,
DL-K11, DL-K15, and DL-K18 contactors after removing
the fixing and connecting elements.
The right-side terminal (L3) of the relay should be put to the
correct position before connecting to the contactor.

The reeveable current-transformer is available between

It can be used for motorstarter, reversing and star-delta
starter combinations with DL-K15, DL-K18, DL-K22...DL-
K132 contactors.
Cross-section of the reeveable wires accross the current
transformer: 25...51 A 25 mm 2 ( 11,5
